<p>Reports <b>catch</b> parameters that are unused in their
corresponding blocks. This inspection will not report any <b>catch</b> parameters
named "ignore" or "ignored".</p>
<p><b>Example:</b></p>
<pre><code>
  try {
      def arr = new int[3]
      arr[5] = 5
  } catch(Exception <b>ex</b>) {
      println('Catching the exception')
  }
</code></pre>
<p>Here the parameter <b>ex</b> is never used in <b>catch</b> block.
<p>After the quick-fix is applied:</p>
<pre><code>
  try {
      def arr = new int[3]
      arr[5] = 5
  } catch(Exception <b>ignored</b>) {
      println('Catching the exception')
  }
</code></pre>
